Also I don't really care what it sounds like outside, I want to hear what it sounds like inside the cabin.

You've probably already seen these videos but just in case you haven't they do have some interior footage with the Akrapovic installed. Granted one also has the Gruppe-M intake installed but I'd assume the sound might be similar.

Also, might be up for questioning how much Active Sound plays a part in the interior sound.

@Bokke - Sorry if I'm thread jacking. Again, a great video you made. Look forward to another one.
